Get the s version. It would be interesting to see time differences on the track both cars.

A type S article will be done soon, as I am taking one to a national race event to see how it fairs :)

To the one deciding on which TT02, if you have experience, try get a sensored motor. I'm not sure if it's the tightness of the drive train (of the tt02)or my sensorless motor but having a race grade buggy plus sensored you're driving something completely different in terms of engineering design and feel

I just got the type R after being "sweet talked" by the shop people
the type S was OOS

non-sensored motors are known for cogging at very low speed or when you are starting to pull the throttle trigger, could be the cause of that feeling of "tightness" on your tt02's drivetrain.

Bought a tt02r for my 10yr old son. He likes doing laps with me down at the local on road track. Thought about getting a tt02s kit also and build one uber tt02 and one beater. Take all the best bits out of the two kits and build a TT02RS?

I studied the manuals for the s spec as I have the r spec as i had the same thoughts as you

generally speaking, you can but there are some issues.

the s spec and r spec's suspension setup is quite different,
r spec uses a double wishbone system. s spec uses a single lower wishbone with camber adjustments.

the s spec allows for camber adjustments while the hop up option for the rear knuckle is set at 2.5degree. though there are option parts (rear metal suspension plate) that seems to allow for 3degree toe in.

the s spec cannot use the r spec's 3 deg knuckle because the rear suspension setup is very different.

the R spec should be able to use s spec's front camber adjustment by replacing a number of parts from s spec.



of course there are aftermarket options from yeah racing etc.

YR might have option parts to give 3deg toe in for the rear knuckles.
I am getting some upper suspension arms that allows for camber adjustment to fit into the r spec that I have.

I ordered both kits. I'll play around with the parts see what I can mix and match.

Trying to find a set of swing shafts for the S version. 42mm is what the dog bones are so does that mean I need 42mm swing shafts? Only 42mm swing shaft kits I could find were tamiya# 54515 for the xv01. Do you guys think they would work for the tt02s?

The tamiya TT02s manual recommends the XV01 front (42mm) universals.

Cool that's the kit I ordered. Thanks!

When using the XV-01 universal shafts (#54515) in the front of a Type S, I found that a spacer is needed between each of the (top) 5 x 9mm ball connectors (BB5) and the F1 / F2 parts (#51293) so that the ends of the ball connectors will not foul and dislodge the wire retaining clips on the universal shafts when the car is in motion. I used a 0.5mm thick spacer on each ball connector, although thinner spacers may suffice.

Took it only a couple of hours to build, 2 hours I guess, max 3. It's very easy to build even for a beginner.

Like another user said, the body is harder. It requires careful spray painting to avoid the paint becoming too heavy.

In case anyone was wondering what the stock f/r camber, and front toe are on the regular tt-02s:

Front camber: -1°
Rear camber: -1°
Front toe: +1°

Pretty sure I couldn't find this info anywhere when I looked a while back, but I've got a well-shimmed type-d on the setup station, and it's solid 1s everywhere. I have the 2.5° rear toe blocks, so not sure what the factory rear toe is.

Is it possible to compete at the local level with a TT02R in a 21.5 USGT class on an outdoor asphalt track? I really like Tamiya products and was wanting to do some touring car racing on a budget. I wasn't sure if the TT02R could be competive or not against more race worthy touring cars. Also, which car do you think would do better a stock TB04 or a TT02R?

Best regards,
Brian
